ABSTRACT

Objective: To examine systemic vascular resistance index (SVRI), asymmetric (ADMA) and symmetric dimethylarginine (SDMA) levels in preeclampsia at different gestations.

Methods: Twenty-four preeclamptic patients (14 at ≥ 34 weeks’) and 72 matched healthy controls were included. SVRI was calculated from impedance cardiography measurements. ADMA and SDMA levels were determined using enzyme-linked immunosorbent assay.

Results: SVRI and SDMA were higher in preeclampsia overall, in early onset and late onset compared to controls. SVRI was correlated with ADMA and SDMA, respectively.

Conclusions: Early-onset and late-onset preeclampsia are both characterized by increased systemic vascular resistance and elevated levels of nitric oxide synthesis inhibitors.
